The chemtrail conspiracy theory seems to frequently misidentify ordinary contrails as “chemtrails” – some kind of secret spraying program. This theory comes in many flavors, and there’s a large number of things people bring up as “evidence” to support this theory. I’ve tried to gather all the debunks of this evidence in one place here, for easy reference. This is a work in progress, and will remain on the front page here as I expand and refine it.

While the title of this post is “How to Debunk Chemtrails”, the actual debunking depends on what version of the theory needs debunking. There’s a variety of common claims, and variations on those themes. The best approach is to debunk the individual claim (such as: contrails only last a few seconds), rather than trying to debunk the entire theory.

I’ve tried to arrange each section in the order of most useful links first.
